Integrate a Third-Party API Into Your BackendWilfried DZADOU
I integrate external APIs and SaaS services into existing backend systems, with attention to reliability, maintainability, and production behavior.
Instead of scattering raw API calls throughout your application, I can design a clean integration layer that handles authentication, data mapping, failures, retries, webhooks, and business workflows.
I can help with:
REST API integrations
OAuth2 and token-based authentication
Webhook ingestion and processing
Data synchronization between systems
API client/service abstractions
Retry, timeout, and failure-handling strategies
Background and event-driven workflows
Mapping external data into your internal domain model
Logging and observability for integrations
Production debugging of existing integrations
I have worked with integrations including Gmail API, Google Cloud Pub/Sub, WhatsApp Cloud API, cloud services, messaging providers, and business-specific third-party systems.
Engagements can range from adding one external API to designing a complete integration workflow between multiple services.
Example work
Gmail API Integration Toolkit
WhatsApp Cloud API integrations
Insurance platform third-party integrations
Google Cloud Pub/Sub workflows
